I think the best point made by the authors is that creating native apps is often avoidable, regardless of what OS you might develop for. Often a website optimized for mobile devices would more than suffice, and would also avoid the proprietary pitfalls of developing for just one OS.

When there's no concrete need to use a device's native abilities, it's foolish to waste time creating a proprietary, limited utility browser for just one device. Even if that device is running Android or iOS.
